The unique west leg of the Pier C intersection has 3 roadways: eastbound vehicular movements to the south, westbound vehicular movements to the north, and a 20’ wide lane in the middle used by automobiles travelling in both directions. The middle lane is protected by K-rails on each side and is accessible only one direction at a time. The driveway from the side street is used for the Matson terminal operation. This intersection was previously controlled by All-Way STOP signs, causing traffic to experience significant delay.
